lM PROVEMENT IN HAY-TEDDERS.

Specification forming part of Letters Patent No. 204,622, dated June 4, 1879;

application filed December 20, 1877.

To all whom it may concern:

Be it known that I, JOHN A. SELLoN, of Belfast, in the county of Allegan y and State of New York, have in vented a new and Improved Hay-Tedder, of which the following is-a specification:

Figure 1 is a vertical section of my improved hay tedder. Fig. 2 is a transverse section taken on line as an in Fig. 1. Fig. 3 is a detail view of the locking device.

This invention has relation to hay-tedders of that class shown in the patent of E. W. Bullard, dated January 31, 1871, No. 111,314; and my improvement consists in the combination of devices, as will be hereinafter more fully set forth, and pointed out in the claim.

Referring to the drawing, A is the axle of the tedder, to which the gear-supporti'n g frame B is attached by clips or bolts.

The shafts G are connected by shaft-couplings or joints a with the axle, and are connected together by cross-bars b c. The ends of the cross-bar c project beyond the shafts for receiving the arms e, to which the upper ends of the springs d are attached. The lower ends of these springs are attached to arms 0, that are bolted to the sides of the frame B. The springs have nearly or quite suflicient strength to raise the front end of the frame B.

A shaft, D, is journaled in standards f, that are secured to the cross-piece c, and to the said shaft two arms, g, are secured, one near each end of the shaft. These arms are connected by connecting-rods h with the front cross-bar of the frame B.

A hand-lever, E, and a toothed sector, F, are placed on the shaft D. The toothed sec tor F is engaged by a spring-detent, a, which is attached to the rear edge of the cross-bar c, and the free end of the spring-detent is provided with an inclined surface, which is engaged by a lever, j, that is pivoted to the top of the cross-bar 0.

Rubber buffers k are attached to the crossbar 0, for preventing the locking of the arms 9 and connecting-rod.

By means of my improvements a considerable amount of labor is saved, and the breakage of the machine is obviated, as it will yield automatically to obstructions.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- The combination, in a haytedder, of the rock-shaft D with lever E, arms 9, connectingrods h, and the rubber buffers k attached to the cross-bar c, substantially as and for the purpose set forth.

JOHN ALLEN SELLON.
